loosing sync when switching resolution

[pacman]

As per topic my HANTAREX MTC 9110 always loose V-sync when switching between games using different resolutions. so that I need to slight adjust the pot.Do you know what this could be ?

I had this problem on my MTC 9000 and I can't remember how I fixed it.

What resolution are you using?

I think you need to configure the mame.ini for your set up.

[pacman]

I am using 640x240 for the desktop (still have to install Mamewah and using MAME32 temporaly);It looks like the V-pot is very sensible...if I just push gently on it then it goes rolling slowly. Vertical games are OK but for many Horizontal game I need to adjust the V-sync

[DaveJ-UK]

Try 640x288 interlaced (I think that's the one)

[pacman]

Well now I am using Mamewah in 640x480 and nothing changed. All my vertical games works fine but many horizontal games require a pot adjustment (I believe many with 240 H lines). I set up INI files with AVRES utility...

Be sure to remove all non 60hz modes when using the util.

Is there any chance to have the correct INI file to be used with AVRES ? ..I mean the one with the best resolution that the utility should pick up for each game?
